It looks like this could work. Keeping the mount centered on the housing will allow use of the right handle for a second strobe or video light and give a better perspective for anything filmed close.

I can start with Ultralight's BA-HB ball adapter in the top of the housing. Hopefully the thread size on the stud matches the threads on the Ike housing. The long clamp AC-CSL will give me a little reach and the ball mount AD-GO will connect to the tripod mount on the GoPro housing.

Thanks for this idea. Now to decide on a camera. The HD3 black looks like the way to go.
